### All replies

• In addition to Cor's reply, even if this is not homework, it is really more of a math problem.  There isn't any special code for dealing with polar coordinate systems built into .Net.  There are standard methods for arithmetic, trigonometry, and calculus.  You will need to already understand polar coordinates and how to perform mathematical operations on them.

• Hi John,

Don't you try first before you reply :-).

It is no Gif, it is the program. Which needs Option Strict Off, but the only change for that is Csng(dt) in 3 places.

Naw. I just like the .Gif of the earth orbiting the sun with the face of the earth facing the sun having sunlight on it and the moon orbiting the earth. Couldn't tell if there was an eclipse or not though, it's too fast! ;)

No. Its not to scale, the times are not the real times etc.

But, it works like a survey instrument where the center is the instrument and the angles are what are read on the survey instrument which is a small telescope and a protractor on a leveled tripod.

The distances are measured with a tape or even steel chains.

Of course today it is mostly a boring old computer on a stick.
